This invention relates to new and useful improvements in a shaker bag cap and' fastener. o

In various recovery systems shaker bags are used which are placed through man-holes into tanks and into which dust, pigments, etc.

are filtered.

It is an object of this invention to construct a shaker bagcap and fastener which is charm acterized by a rigid-member placed beneath d .the closed head of a shaker bag, a second rigid member above the head of the shaker bag, and means to clamp the members to.- gether whereby the shaker bag is held in an opened position and may conveniently be thus suspended.

' A still further object of this invention is the provision of the rigid members in the form of discs for engaging in shaker bags 2 which are circular in transverse cross section.

'This invention has fora still further object the provision of a hand member at-" tached upon the top of the rigid member for engaging some supporting element to accom- I be lifted and heldin place with=the use of one hand only. a y

This invention has for a stillfurther object the provision of a fastener for a shaker bag which is characterized by a perpendicular portion having a head portion extended directlyover 'a'peg for engagementin an aperture ofa gridiron or support, bearings connected with the perpendicular portion to limit possible swinging of the bag, and a spring ooacting with-the bag to hold the fastener in place when engaged upon the gridiron. I This invention has for-a still further objectthe provision of a means for moving the head portion and the peg of the fastening means sothat it may.v be released'with one hand. 7 A. still further object'of this invention is the construction of a shaker bag and fas- 50 tener which is of simple durable construe sold at a reasonablecost.

Fig. 7 is a view similar to Fig. 5, butillustrating a modification, and I Fig. '8 is a fragmentary elevational view looking'in the direction of the line 88 of Fig.7. iv

The shaker bag cap and fastener 'according to this invention comprises a rigid member 10 located beneath the closed head 11,0f a shaker bag 12. A. second rigid member 13 is located above the head 11, and a means is provided for clamping these rigid: members firmly together so as to hold the'shaker bag in an opened position. The means referred to comprises a bolt 14 engaged through'the rigid members and provided with a clamping nut 15. 1 ;v 1

As shown on the-drawing, theshaker bag 12 is of circular construction in transverse .cross section. A plurality ofring shaped rims 16 are attached upon the circumference j for supporting the bag. "This fastening means is in the form of a bracket consisting of a perpendicular portion 18 having a-hori zontal projecting head portion 19,. A, base portion 20 connects with the lowe'r end of'the perpendicular portion and is formed "with .a

plurality of bearing surfaces'21 to' limi t possible swinging of thesuspendedbagupon; a gridiron 22 whichj'is provided with'anapert'ure 23through which a peg 2i engages. The peg 24 projects from the perpendicular portion 18. A plurality of bolts '25 engage h through" the bearing surfaces21 and the rigid membersl'O and "13 and serve toholdthe fas-- f 'tening means upon the rigid members, and,

the'rigid members in placeupon the bag.

-Aspring 26 is attached at its "bottom end "by a screw25 uponalportion of'theubasek20 of the fastener bracket. 'This spring is 1 curved and actsagainstthe outer endof the peg 24 and. the edge or the head portion19. :The spring 26 is'of-a length so: that its top' "end 27 projects slightly above thetop face.

of the headportion'19. yThe apertur'e '23 is. of such a size as to be sma ller than the width i of the head portion 19 so that when the shaker bag is moved upwards against the sltationary ridiron 22 and riesin between t espring 5 andpthehead Sermon e h a p !sides of said head, means for clampin they cannot engage through the opening 23-. Con 'sequently, it ,is: necessaryf-that the shaker;

The shaker bag is then free from the grid iron.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein maybe made. I therefore reservethe right andprivilege of changin the formof th'e'detailsof construction or ot erwise altering-the arrangement of the correlated parts without departing, from the spirit or the scope of the appended claims. r ,Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is l. A shaker bag, comprising a bag having aclosed' head, rigid niembers'on opposite sides of sai'd'head, means'for clamping the rigid members together, and means for sup-r porting the rigid members upon some support comprising a fastener consisting of a 'vertical portion having a head portion, a'base portion projecting from'the bottom'of the vertical portion and attached-upon the top of the rigid members, apeg projecting from the vertical portion for engaglng in an aperture of a gridiron andlo'cated below said head portion so that the top edge of the gridiron 'mjay engage the head portion to hold the shaker bag against "swinging," and a spring attached uponthe base portion and extend-.

ing over the peg andthe head-portion.

a clo'sedhead, rigid members on opposite rigid members together and means forsupporting the rigidmembers upon some sup port; comprising :a. fastener consisting of a vertical portion having a head portion, a base portion projecting from the-bottom ofthe vertical portion and attached upon the top of the rigid members, a peg projecting from the ranged upon said base portion foracting against'the bottom of said gridiron so that 2. A shaker bag, comprising a bag having the head portion may act against the top of the gridiron and limit possible swingingof the bag. I

'3. A shakerbag, comprising a bag havinga closed head, rigid members on opposite sides members together, means for supporting, the rigid members upon some support comprising a fastener cons sting of a vertlcal portion having a head-portion, a base portion projeoting from the bottom of the vertical portionand attached upon the top of the rigid members, a'peg projecting from the vertical portion for engaging in an aperture of a gridiron, and a spring attached upon the base portion and extending over thepeg and the head po-rtion,-the vertical portionbeing movable withregards to the base portion -so that the head portion and peg may be retracted to release the bag.
